Water Nitrate Testing
September 6 @ 9:00 am - 4:00 pm
Free and confidential water nitrate level testing is provided by the Coles County SWCD on the first Wednesday of every month. To test your farm’s tile drainage water, simply bring in a sample and receive your results.
- Sample containers should be clean and free of any residual chemicals or detergents.
- Samples need to be at least 8 oz.
- Samples should be taken as close to the testing time as possible (preferably within 48 hours) and be kept refrigerated if not being tested immediately.
- An estimate of flow will allow additional calculations (load in lbs/day) – simply record the seconds it takes to fill up a bucket of a known volume.
For more information, call the office at 217-345-3901 ext. 3.
